Hai River


imageHai River

The Hai River, formerly known as the Peiho or Pei Ho, is a Chinese river connecting Beijing to Tianjin and the Bohai Sea.

The Hai River at Tianjin is formed by the confluence of five rivers, the Southern Canal, Ziya River, Daqing River, Yongding River, and the Northern Canal. The southern and northern canals are parts of the Grand Canal. The Southern Canal is joined by the Wei River at Linqing. The Northern Canal joins with the Bai He (or Chaobai River) at Tongzhou. The Northern Canal (sharing a channel with Bai He) is also the only waterway from the sea to Beijing. Therefore, early Westerners also called the Hai He the Bai He.

At Tianjin, through the Grand Canal, the Hai connects with the Yellow and Yangtze rivers. The construction of the Grand Canal greatly altered the rivers of the Hai He basin. Previously, the Wei, Ziya Yongding and Bai Rivers flowed separately to the sea. The Grand Canal cut through the lower reaches of these rivers and fused them into one outlet to the sea, in the form of the current Hai He.

Hai He is 1,329 kilometres (826 mi) long measured from the longest tributary. However, the Hai He is only around 70 kilometres (43 mi) from Tianjin to its estuary. Its basin has an area of approximately 319,000 km2 (123,000 sq mi). Its annual flow is only half that of the Yellow River, or one-thirtieth that of the Yangtze River.

In 1863 seagoing ships could reach the head of navigation at Tongzhou, but the crooked river was difficult for large vessels. During the Boxer Rebellion, Imperial Chinese forces deployed a weapon called "electric mines" on June 15, at the Baihe river before the Battle of Dagu Forts (1900), to prevent the western Eight-Nation Alliance from sending ships to attack. This was reported by American military intelligence in the United States. War Dept. by the United States. Adjutant-General's Office. Military Information Division.

Juma River (China)


Juma River (Chinese: 拒马河; pinyin: jùmǎhé; literally: "Stop the horse") is a river in northern China that emerges from a spring-fed lake in Laiyuan County, Hebei Province and flows to Fangshan District in Beijing Municipality before emptying into the Daqing River, a tributary of the Hai River. The length of the river is approximately 254 km. At Shidu, the meandering river creates a deep valley in the scenic karst landscape. At Zhangfang, the river forks into the Northern and Southern Juma, both of which flow into the Daqing. The Beijing–Yuanping Railway follows the Juma River through the Taihang Mountains.

Coordinates: 39°31′24″N 115°06′54″E / 39.5234°N 115.1150°E / 39.5234; 115.1150

Yongding River


The Yongding River (simplified Chinese: 永定河; traditional Chinese: same; pinyin: Yǒngdìng Hé; Wade Giles: Yungting River) is a river in northern China. It is one of the main tributaries in the Hai River system and is best known as the largest river to flow through Beijing Municipality. In recent year, the Beijing segment of the river has dried up due to environmental issues. Beijing Municipality government has invested 16 billion yuan in effort to replace the riverbed with parkland or smaller bodies of water.

The Yongding River is 650 kilometres (400 mi) in length and drains an area of 47,016 square kilometres (18,153 sq mi). It emerges from the Guancen Mountains (管涔山) in Ningwu County, Shanxi Province, where it is known as the Cangqian River (桑乾河) and flows northeast into Inner Mongolia and then heads southeast into Hebei Province.

In Huailai County, it fills the Guanting Reservoir, the biggest reservoir serving Beijing and takes on the name Yongding. It enters Beijing Municipality through the Xishan Mountains west of the city in Mentougou District and descends into the flatlands of Fengtai and Daxing Districts.

The river eventually flows back into Hebei Province and then on to Tianjin Municipality, where it meets the Hai River just before the latter enters the city and then empties into the Bohai Sea at Tanggu. Part of the river is diverted before the juncture with the Hai, and flows directly into the Bohai Sea. This channel is called the Yongding New River (永定新河).
